LUG-STRAP FOR IPICKER-STICKS.

ject is to provide a new and improved lug strap for picker sticks,arranged to insure a proper transmission of the power applied to thepicker stick, to prevent accidental shifting of the lug strap of thepicker stick, and to avoid weakening of the picker stick by holes,notches or the like.

For the purpose mentioned use is made of sweep straps carrying astriking member between them, links pivotally connected with the saidstraps, and a support on the picker stick and on which the said linksare pivi oted.

A practical embodiment of the invention is represented in theaccompanying drawings forming a part of this specification, in whichsimilar characters of reference indicate corresponding parts in all theviews.

Figure 1 is a side elevation of the lug strap as applied to a pickerstick; Fig. 2 is an edge view of the same; Fig. 3 is a sectional sideelevation of the same, parts being broken out; and Fig. 4 is a sectionalplan view of the same on the line 44 of Fig. 1.

To the outer side of a picker stick A of the usual construction isclamped a support B by the use of a clamp C, and the said support B ispreferably formed of a bar provided at its upper end with atransversely-extending pivot pin D on which are pivoteddownwardly-hanging links E pivotally engaging pivots F held on the sweepstraps G spaced apart to permit the free passage of the picker stick Aand the support B between the said straps G. The inner ends of the sweepstraps G are connected by a transversely-extending bolt H with the sweepstick I connected with the usual machinery for imparting the desiredmotion to the picker stick A, as hereinafter more fully explained. Theouter ends of the sweep straps G support a transverse bolt J on which ismounted a striking member K, preferably formed of disks of leatherfabric, or other material, to give a cushion- Specification of LettersPatent.

1 ing effect to the striking member at the time the latter engages theouter side of the support B. When the sweep stick I is moved inward inthe direct-ion of the arrow a then the sweep straps G move with thesweep stick and as the said straps G are hung on the swinging links E,it is evident that the striking member K finally comes in contact withthe outer side of the support B and thus imparts a swinging motion tothe support B and the picker stick A on which the said support B isfastened;

hen the sweep stick I moves in the inverse direction of the arrow a andthe picker stick A is returned to its outermost position in the usualmanner then the several parts again assume the position shown in Fig. 1,that is, the picker stick A can safely return without danger of bindingof the parts of the lug strap owing to the links E pivotally supportingthe straps G. The sweep straps are preferably provided with severalapertures G for the passage of the bolt H so as to permit of properlyadjusting the straps G relative to the sweep stick I.

The clamp C is preferably constructed as follows: Through a yoke C"extends the picker stick A and the lower end of the support B and in theyoke is mounted a shoe or a saddle C seated on the outer side of thesupport B and pressed inward against the same by a screw C screwing inthe outer end of the yoke C. The shoe C is provided with a guideway Cengaged by the outer end of the yoke C so as to prevent accidentaldisengagement of the yoke C and the shoe C The shoe C is furtherprovided with a pin C which extends through the support B and engages arecess A formed in the outer side of the picker stick A, so that whenthe screw C is screwed up the shoe C is firmly pressed in contact withthe support B whereby the latter is clamped in position on the pickerstick A and up or down slipping of the support B is prevented, owing tothe pin C engaging the recess A. i

It will be noticed that by the arrangement described the support B canbe readily adjusted up or down on the picker stick A according to theposition of the sweep stick I so that the latter and the straps G arearranged in proper alinement and after the support B has been moved tothe desired position it is securely fastened in place by the operatorscrewing up the screw C to clamp the support B in place on the pickerstick A by the clamp C.

The lug strap shown and described is very simple and durable inconstruction, can be readily adjusted up or down on the picker stick andrequires no weakening of the picker stick by boring holes or the like inthe picker stick.

The support B is preferably in the form of a bar and as it is clamped tothe picker stick A at the very points where the most strain is exertedit is evident that the picker stick is reinforced by the said bar, andhence the picker stick is not liable to break or split.

In order to properly space the links E from the picker stick A and thesupport B use is made of washers D mounted on the pivot pin Dintermediate the support 13 and the links E, as plainly indicated inFig. 2.

It is understood that the lug strap may be readily used on narrow orWide picker sticks.

Having thus described my invention, I

claim as new and desire to secure by Letters 5 Patent of said sweepstick, and between which the said picker stick extends, a strikerextending between the outer ends of said straps, a supporting baradapted for connection upon the outer edge of the picker stick toreceive the impact of said striker, links pivotally con-- nected to saidsupporting bar and to said sweep straps whereby to support the latter,and a clamp surrounding the picker stick and said bar for securelyholding the latter in proper position.

2. The combination with a picker stick, of a bar disposed upon the outeredge thereof and provided with a transverse opening, a plate having aspur adapted to extend through the bar opening and into engagement withthe picker stick, a yoke adapted to surround the picker'stick, bar andspur plate, and a set screw threaded through the yoke and adapted tobear against the spur plate.

In testimony whereof I have signed my name to this specification 1n thepresence of two subscribing witnesses.
